Hello. I am aware of the fact that systemd relies on the kernel to set system clock from hardware clock, and that requires compiling rtc drivers into the kernel, not as modules. I am also aware that doing it othervise would mix timestamps in log entries. The question is: if I have rtc driver as a module anyway, how to modify initramfs so that system time would be set, in such a way so that it happens *before* journald in initramfs starts? I assume it is an initramfs using systemd inside of it. One approach would be to have an udev rule that does trigger after rtc appears or rtc symlink is added, this rule would start a service that sets the system clock, but this service would have to always run before journald, and that seems not possible in such a configuration, because if someone would unplug the rtc the service would not run? Another thing is to load rtc and i2c bus module where rtc is connected statically without udev detection, and then the hwclock service would always be triggered before journald without looking for rtcs appearing...
